Automated Personnel Screening System and Method

ABSTRACT

The present specification discloses a system for controlling a movement of at least one person into a controlled location. The system includes an X-ray screening system having an entrance area defined by walls and a gate, and an exit area defined by walls and a gate. The gates are automatically controlled based upon the output of the X-ray screening system. Additional gates, defining an additional holding area, are used for subsequent analysis and inspection.

FIELD OF THE INVENTION

The present invention relates generally to the field of X-ray screeningand more specifically to systems and methods of managing the flow ofpeople through personnel screening systems, which include X-ray basedpersonnel screening systems, in order to optimize overall throughput andstaffing needs.

BACKGROUND OF THE INVENTION

People screening systems, which can be X-ray, active millimeter wave, orpassive millimeter wave based and metal detector systems, are deployedat transit points to detect contraband and threat items, such asweapons, explosives, and other dangerous objects concealed underclothing and within clothing. There exist a wide range of threat items,which are difficult to be automatically and conclusively detected by anautomated algorithmic-based X-ray scanned image analysis system, leadingto high false alarm rates.

In conventional systems, an operator is required to identify very lowcontrast objects. The difficulty of this task results in poor detectioncapability for a wide range of contraband and threats composed of lowatomic number elements, such as plastics or ceramics, because they areoften masked by the low atomic number elements that comprise the humanbody. Algorithmic-based image analyses such as edge detection or contoureffects may be used for automatically and uniformly enhancing the imageedges of low atomic number concealed objects to facilitate theirdetection. However, such edge enhancement is often accompanied with asimultaneous suppression of the edges of internal human anatomy thatproduce confusion in image interpretation.

However, a full body pat-down search is often time-consuming,resource-intensive, and uncomfortable for both the security personneland the subject under inspection. The time consumed in performingfull-body pat-downs further decreases throughput, thus making theprocess slow and inconvenient for other subjects who are in queue forsecurity screening.

Accordingly, there is need for an integrated process for effectivelymanaging the flow of people through various screening procedures,including a people screening system, such as, but not limited to, anautomated people screening system, manual screening system, or anX-ray-based people screening system, operator intervention through scanimage review, and pat-down search by security personnel in a way thatoptimizes overall throughput and staff requirements.

SUMMARY OF THE INVENTION

The present specification discloses a system for controlling a movementof at least one person into a controlled location, where the at leastone person, in various embodiments is one of a single adult, a childcapable of walking alone, an adult with a child that needs assistancewalking, or a disabled adult with another adult assistant/caregiver thatassists the disabled adult in walking or by pushing on the disabledadult's wheelchair comprising:

-   -   A personnel screening system, such as an X-ray based screening        system, having an entrance area defined by a plurality of walls        and an exit area defined by a plurality of walls;    -   A first gate having a first state and a second state wherein, in        the first state, the first gate is open permitting entry of the        at least one person into said entrance area and wherein, in the        second state, the first gate is closed preventing entry of the        at least one person into said entrance area;    -   A second gate having a first state and a second state wherein,        in the first state, the second gate is closed preventing the        person from leaving the exit area and, in the second state, the        second gate is open permitting the person to leave the exit        area;    -   A third gate having a first state and a second state wherein, in        the first state, the third gate is closed preventing the person        from leaving the exit area and, in the second state, the third        gate is open permitting the person to leave the exit area and        enter a holding area; and    -   The X-ray screening system generates data, either automatically        or manually, indicative of whether said person is carrying a        prohibited object; and    -   The data is used to automatically open at least one of said        second gate or third gate.

Optionally, if said data is indicative of said person carrying aprohibited object, said X-ray screening system automatically transmits asignal to the third gate to open the third gate and permit the person toleave the exit area and enter the holding area. The X-ray screeningsystem does not transmit a signal to the second gate to open the secondgate if said third gate is being opened.

Optionally, if said data is not indicative of said person carrying aprohibited object, said X-ray screening system automatically transmits asignal to the second gate to open the second gate and permit the personto leave the exit area. The X-ray screening system does not transmit asignal to the third gate to open the third gate if said second gate isbeing opened.

The holding area is defined by a first wall, a second wall, the thirdgate, a fourth gate, and a fifth gate. In one embodiment, the fifth gateis a door. The fourth gate has a first state and a second state wherein,in the first state, the fourth gate is closed preventing the person fromleaving the holding area and, in the second state, the fourth gate isopen permitting the person to leave the holding area. The fifth gate hasa first state and a second state wherein, in the first state, the fifthgate is closed preventing the person from leaving the holding area and,in the second state, the fifth gate is open permitting the person toleave the holding area and enter an inspection area. The data iscommunicated to a station for analysis by a remote screener. The remotescreener indicates, using the station, where to look on the subject'sbody for the potential threat item.

In one embodiment, the data (indicative of the potential threat) issuperimposed on an avatar (instead of over an X-ray image of thesubject's body) to maintain privacy. United States Patent PublicationNumber 20100034451 and U.S. Pat. No. 7,796,733, both assigned to theassignee of the present invention, are herein incorporated by referencein their entirety. The station is configured to transmit a signal tosaid fourth gate or said fifth gate based upon receiving an input fromsaid remote screener. The station transmits a signal, based upon aninput from said person, to open said fourth gate, if said persondetermines that said data is not indicative of said person carrying aprohibited object. The station does not transmit a signal to the fifthgate to open said fifth gate if said fourth gate is being opened. Thestation transmits a signal, based upon an input from said person, toopen said fifth gate, if said person determines that said data isindicative of said person carrying a prohibited object. The station doesnot transmit a signal to the fourth gate to open said fourth gate ifsaid fifth gate is being opened. The inspection area is defined by athird wall, a fourth wall, and the fifth gate. At least one of saidfirst gate, second gate, third gate, fourth gate, or fifth gate ispartly controlled by a motion sensor.

In another embodiment, the system for controlling a movement of at leastone person into a controlled location comprises an X-ray screeningsystem having an entrance area defined by a first wall, a second wall,and a first gate and an exit area defined by a third wall, a fourthwall, a second gate and a third gate, wherein said X-ray screeningsystem generates data indicative of objects being carried by saidperson; and a controller in data communication with said X-ray screeningsystem wherein said controller automatically opens at least one of saidsecond gate or said third gate based upon said data. If said data isindicative of said person carrying a prohibited object, said X-rayscreening system automatically transmits a signal to the third gate toopen the third gate and permit the person to leave the exit area andenter a holding area. If said data is not indicative of said personcarrying a prohibited object, said X-ray screening system automaticallytransmits a signal to the second gate to open the second gate and permitthe person to leave the exit area. The holding area is defined by afirst wall, a second wall, the third gate, a fourth gate, and a fifthgate.

These, and other embodiments, will be further understood when consideredin light of the detailed description read in combination with thedrawings.

Language used inthis specification should not be interpreted as a general disavowal ofany one specific embodiment or used to limit the claims beyond themeaning of the terms used therein. The general principles defined hereinmay be applied to other embodiments and applications without departingfrom the spirit and scope of the invention. Also, the terminology andphraseology used is for the purpose of describing exemplary embodimentsand should not be considered limiting. Thus, the present invention is tobe accorded the widest scope encompassing numerous alternatives,modifications and equivalents consistent with the principles andfeatures disclosed. For purpose of clarity, details relating totechnical material that is known in the technical fields related to theinvention have not been described in detail so as not to unnecessarilyobscure the present invention.

FIG. 1 a shows an automated single-flow personnel screening system 100in accordance with one embodiment of the present invention. System 100comprises a X-ray scanner 110 for scanning people along with a pluralityof automated gates/doors positioned before and after the scanner 110 toguide and direct a flow of people through the system 100. In oneembodiment, scanner 110 is a dual-sided backscatter X-ray peoplescreening system such as the Rapiscan Secure 1000 Single Pose systemcommercially manufactured by the assignee of the present application.The people screening system can be any screening system capable ofconducting an interrogation of a person and his or her belongings. Suchscreening systems can include any of the systems disclosed in U.S. Pat.Nos. 5,181,234; 6,094,472; 7,418,077; and 7,660,388; U.S. patentapplication Ser. Nos. 11/032,314; 12/262,631; 12/344,162; 12/024,320;12/142,978; and U.S. Provisional Patent Application Nos. 61/313,773;61/313,772; 61/261,818; and 61/262,176, which are all incorporatedherein by reference in their entirety.

In one embodiment, system 100 is capable of managing a single stream ofpeople and comprises at least three automated gates/doors to direct theflow of personnel. In one embodiment, the automated gates/doors comprisea first gate 105 situated prior to the scanner 110 that acts to create,in combination with side walls 111 an entry area 109 to the system 100ensuring, for example, that only one person at a time enters the scanner110. Gate 105 opens when a person approaches and then closes when theperson passes the open gate 105, remaining closed at least while theperson is being scanned. Second and third gates 115, 120, respectively,are located immediately after the scanner 110 to direct the person, whois held in hold area 112 post scan, in one of two different areas 135 or122 based on the outcome of automatic scan. Optional fourth and fifthgates 125, 130, located further downstream from the scanner 110, directthe scanned person, who is held in hold area 122, in one of twodifferent directions 135 or 145, respectively. An operator 102 can viewscanned image, from scanner 110, to ascertain if the image scan isbenign or comprises anomaly—in case the system 100 is unable toautomatically provide clearance to the person. In one embodiment, theoperator 102 is presented with an avatar (instead of an actual X-rayimage of the scanned person comprising anatomical details) with anomaly,if present, superimposed on the avatar. The use of the avatar allows formaintaining of the scanned person's privacy.

It should be appreciated that the gates 105, 115, 120, 125, 130 can bestructured or configured using any form of door or gate. In oneembodiment, gate 105 comprises two panels 108, which are a left paneland a right panel, that open and close in a coordinated fashion. Thepanels 108 are hinged to side walls 111 that extend from each of thegate panels 108 to X-ray scanner 110 to create an enclosed area 109. Inone embodiment, the gate 105 opens automatically a) based upon a signalreceived from an infrared sensor, or other type of motion sensor, thatdetermines when a person is sufficiently physically proximate to thegate panels 108 and b) if the system 100 indicates that another personis not in the personnel X-ray scanner 110 and, optionally, not in theexit hold area 112. The gate 105 can then automatically close once amotion sensor detects the person has passed into entry area 109. Inanother embodiment, the gate 105 can be a unitary structure (made of alarge single panel), can be a rotating or revolving door, can be solid,can be transparent, or can be made of any material known to persons ofordinary skill in the art.

In one embodiment, gate 120 and gate 115 each comprise a single panelthat opens and closes in a coordinated manner. Gate 115 meets left sidewall 113 a, which extends from the X-ray scanner 110 to create a firstportion of the enclosed area 111. Similarly, gate 120 meets right sidewall 113 b that extends from the personnel X-ray scanner 110 to create asecond portion of the enclosed area 111. Gates 120 and 115 arepreferably both hinged to a common location which is physically part of,or attached to, left side wall 116. The common hinge point enables gate120 and gate 115 to both open out and away from exit area 112,specifically in pathway 135 and into hold area 122, thereby avoidingopening inward and potentially hitting a person standing in exit area112 and avoiding opening and hitting each other. To ensure traffic flowis properly directed, only one of gates 115, 120 is open at any giventime. Either of gate 115 or gate 120 opens preferably in response to anautomatically generated or manually generated signal, as furtherdescribed below.

The left wall 113 a, gate 115, wall 116 a, gate 125, and wall 117 a forma contiguous enclosure, when the gates are closed. Similarly, the rightwall 113 b, gate 120, wall 116 b, gate 130, and wall 117 b form acontiguous enclosure, when the gates are closed. Gate 125 is hinged towall 116 a and preferably opens away from hold area 122 into trafficflow area 135. Gate 130 is hinged to either wall 116 b or 117 b andpreferably opens away from hold area 122 into traffic flow area 145.

Referring now to FIG. 1 b, during operation, as a person enters system100, he approaches the first gate 105 that automatically opens when theperson is in proximity to the gate 105 (provided no other person is inthe X-ray screening system 110 or, optionally, exit hold area 112),allowing the person to enter and then automatically closes behind himwhile the person is being scanned by the scanner 110. Post scan, theperson steps into hold area 112 while the scanner 110 processes theimage scan. In one embodiment, at this stage, the processing of theimage scan of the person is solely algorithm-based, without requiringany operator intervention, thereby resulting in an automated clear orno-clear outcome from the scanner 110. In case of the scanner 110generating an automated clear result, a signal is transmitted, in awired or wireless fashion, to the second gate 115 to thereby cause amotor to automatically open gate 115, keeping the third gate 120 closed.This permits a person in exit area 112 to exit to clearance area 135from where he is free to exit the entire system 100.

However, if the scanning system does not automatically generate a clearsignal and, instead, generates a no clear signal, (because, for example,the scanner 110 has identified an anomaly), then a signal istransmitted, in a wired or wireless fashion, to the gate 120 to therebycause a motor to automatically open gate 120, keeping the gate 115closed, and the person is directed into hold area 122, as shown in FIG.1 c. This permits a person in exit area 112 to exit into hold area 122.It should be appreciated that, after a user passes any gate, a motionsensor senses the user has past the gate and causes the gate to returnto a closed position, which is a default position or first position inthe system 100. It is expected that the system will process individualsin a pipeline fashion, permitting more than one adult person to enterthe system at a time but only permitting one adult person to be in onedefined holding area at one time. In one embodiment, one adult personand one child that must be accompanied by an adult when walking throughthe screening system can be in one defined holding area at one time, butnot more than one adult. In another embodiment, a disabled adult personand a caregiver or another adult assistant that must accompany thedisabled adult when walking (or, say, being pushed on a wheelchair) canbe in one defined holding area at one time, but not more than twoadults. It should also be appreciated that the system ensures thatpeople are singulated when passing through the system of the presentinvention. In one embodiment, the holding areas are bomb proof therebyeffectively enabling singulation of persons carrying threats.

Once the gate 120 opens and the user moves to hold area 122, an X-rayscreening operator 102 reviews the scan image(s) of the person. In oneembodiment, the scanned image provided to the operator for review ismarked or annotated for areas of anomaly. In another embodiment, anavatar, marked or annotated for areas of anomaly, is presented to theoperator for review. If the operator 102 finds that the anomaly, due towhich the scanner system 100 had not given an auto-clear, is benign thenthe operator causes a signal to be transmitted, in a wired or wirelessfashion, to gate 125 to thereby cause a motor to open gate 125, keepinggate 130 closed. This directs the person from area 122 into theclearance area 135 where he is free to exit the system 100, as shown inFIG. 1 c.

However, if during the review of the scan image(s) the operator 102detects a threat, then instead of causing a signal to be transmitted, ina wired or wireless fashion, to gate 125 to thereby cause a motor toopen gate 125, the operator causes a signal to be transmitted, in awired or wireless fashion, to gate 130 to thereby cause a motor to opengate 130, keeping gate 125 closed. This directs the person towards area140 where security personnel 145 conduct a further physical search ofthe person, as shown in FIG. 1 d. In one embodiment, the furtherphysical search of the person includes a thorough search of the area inquestion. First, the person under inspection will be asked to remove thesuspicious item and show it to the operator. Then, the place on thesubject's body where the item was located is then subject to a limitedarea pat-down. In another embodiment, the further physical searchincludes a full hand/pat-down search of the entire person.

Persons of ordinary skill in the art should note that the operator 102in one embodiment is stationed within or in proximity to the system 100.In alternate embodiments, the operator 102 is stationed remotely fromthe system 100 and is able to communicate with system 100 through wiredand/or wireless network, as would be evident to those of ordinary skillin the art. Also, to further improve the overall throughput of thesystem 100, people to be screened are appropriately pipelined, in oneembodiment.

FIG. 2 is a flow chart describing a method of managing screening ofpeople in accordance with an embodiment of the present invention. As aperson approaches 205 the system 100 of FIG. 1 a, a first gateautomatically opens 210 thereby letting him into an entry area and theX-ray scanner. The first gate closes behind the person while thescanning system is on. After the scan, the person is made to wait 215 ata first hold area to allow for the scanner to algorithmically processand analyze the scanned images for potential threats. If the person isfound to have no suspicious threats, a second gate opens 220automatically leading the person to a clearance area. However, in caseof anomaly a third gate opens 225 instead, keeping the second gateclosed, directing the person to wait 230 at a second hold area while anoperator reviews the scanned images or an avatar marked/annotated forareas of potential anomaly. If the operator finds the anomaly to bebenign a fourth gate opens 235 leading the person to the clearance/exitarea. However, if the operator is unable to take a clear decision byreviewing the scan images and suspects an anomaly then a fifth gateopens 240, keeping the fourth gate closed, leading the person to anotherarea where a pat-down hand search is conducted by security personnel.

FIG. 3 shows an automated dual-flow personnel screening system 300 inaccordance with another embodiment of the present invention. System 300comprises a people X-ray scanner 310 along with a plurality of automatedgates/doors before and after the scanner to guide and direct people whoapproach the system 300 in two streams or pipelines 303, 304. In oneembodiment, the scanner 110 is a dual-sided backscatter X-ray peoplescreening system such as the Rapiscan Secure 1000 Single Pose systemcommercially manufactured by the assignee of the present application.

In one embodiment, system 300 comprises seven automated gates/doors todirect the flow of two streams or pipelines 303, 304 of people. Theseautomated gates/doors comprise a first gate 305 situated prior to thescanner 310 and acts as an entry point to the system 300. As describedabove, the first gate 305 ensures that only one person, from one of thetwo streams or pipelines 303, 304, at a time enters the scanner 310 suchthat the gate 305 opens when a person approaches and closes behind whilethe person is being scanned. Post scan, the scanned person is held inarea 312 while the system 300 automatically processes the image scan forthreat detection. If the scan image processing indicates that there isno threat or anomaly then an auto-clear signal is generated. This causessecond and third gates 315, 320 located immediately after the scanner310 to open thereby directing the person, who was waiting in hold area312 post scan, in any one of two directions 355, 360 leading to aclearance or exit.

However, if the automatic image scan process does not result in anauto-clear signal, fourth gate 325 opens (keeping second and third gates315, 320 closed) directing the scanned person to move to area 322. Whilethe person is held in area 322, one of the two operators 302 views andanalyses the person's scanned image to ascertain anomaly. In oneembodiment, the scanned image provided to the operator for review ismarked or annotated for areas of anomaly. In another embodiment, anavatar, marked or annotated for areas of anomaly, is presented to theoperator for review. Persons of ordinary skill in the art should notethat the scanned image of the person can be directed to any one of thetwo operators 302 depending, in one embodiment, on a predeterminedalternating sequence or, in another embodiment, simply depending onwhich operator has fewer number of image scans queued for analysis. Ifthe operator determines that the anomaly is benign then the operatorsignals fifth and sixth gates 330, 335 to open thereby directing theperson to move in any one of two directions 355, 360 leading to aclearance or exit. However, if the operator determines that the anomalyis likely to be a threat then the operator signals seventh gate 340 toopen (keeping the fifth and sixth gates 330, 335 closed) therebydirecting the person to area 345 where security personnel 350 conduct ahand/pat-down search of the person.

In one embodiment, the system 300 is structured as a series of walls andgates that create a plurality of staged enclosures. A left side of theplurality of staged enclosures is created by a left panel of gate 305,which is hinged to wall 306 that extends to X-ray screening system 310,thereby creating the left portion of an entry area. Wall 308 extends outfrom X-ray screening system 310 to gate 315, which is hinged thereto andopens outward into traffic flow area 355. When closed, gate 315 meetsthe point at which gate 325 meets wall 350 a when closed and forms theleft portion of exit area 312. Gate 330 is connected to, or hinged to,wall 350 a, thereby forming the left portion of hold area 322. Gate 330opens outward into traffic flow area 355. When closed, gate 330 meetswall 351 a, which forms the left portion of pathway 345.

Similarly, a right side of the plurality of staged enclosures is createdby a right panel of gate 305, which is hinged to wall 307 that extendsto X-ray screening system 310, thereby creating the right portion of anentry area. Wall 309 extends out from X-ray screening system 310 to gate320, which is hinged thereto and opens outward into traffic flow area360. When closed, gate 320 meets the hinge point connecting door 325 towall 350 b and forms the right portion of exit area 312. Gate 335 isconnected to, or hinged to, wall 350 b, thereby forming the rightportion of hold area 322. Gate 335 opens outward into traffic flow area360. When closed, gate 335 meets the hinge point connecting gate 340 towall 351 b, which forms the right portion of pathway 345. Gate 340 opensoutward, away from hold area 322 into traffic area 345.

In one embodiment, the system 300 also comprises a plurality of CCTVcameras that provide video feeds, of the streams 303, 304 of people, tooperators 302 to monitor and effectuate opening of appropriate exitgates all the way along the system 300.

Various changes could be made in the above constructions withoutdeparting from the scope of the invention, therefore, it is intendedthat all matter contained in the above description should be interpretedas illustrative and not as limiting. In particular, it should beappreciated that various forms of gates, doors, walls, enclosurestructures, motorized gates, and data signals can be used to achieve thecontrolled traffic flow described herein.
